摘要

为解决城市隧道运营过程中隧道洞外亮度L₂₀(S)全天逐时变化差异大且实时获取困难的问题，结合3D打印隧道缩尺模型，提出以太阳辐照度为输入变量，将天空亮度、地面景物亮度耦合的L₂₀(S)实时计算方法。以北京芦花路隧道为测量对象，利用隧道缩尺模型代替实际隧道探究地面景物亮度变化规律，建立地面景物亮度与太阳辐照度的量化回归模型；利用太阳辐照度将CIE模型、Perez模型的计算值与实测值进行对比验证，以误差较小、计算较简便的CIE模型作为天空亮度模型，其误差在晴天工况和阴天工况下分别为4.26%、6.11%。对比耦合后的L₂₀(S)计算模型在不同季节、不同天气条件下的计算值与实测值，平均误差均在10%以内，表明该隧道洞外亮度实时计算方法在全季节、全气候条件下具有准确性和适用性。

Abstract

The luminance L₂₀(S) varies considerably from time to time throughout the day and obtaining its value in real-time during urban tunnel operations is challenging. Thus, the authors propose a real-time calculation method that takes solar illuminance as the input variable and couples the sky and ground scene luminance into L₂₀(S) in combination with a three-dimensional (3D) printed tunnel scaled model. The Luhua road tunnel in Beijing is taken as the measurement object. A 3D printed tunnel scaled model is used instead of an actual tunnel to explore the change rule of ground scene luminance, and a quantitative regression model of ground scene luminance and solar illuminance is established. The calculated values from the International Commission on Illumination(CIE) and Perez models are compared with the measured values based on solar illuminance in the present study. The CIE model with a smaller error and easier calculation is determined as the sky luminance. The error rates are 4.26% and 6.11% under sunny and cloudy conditions, respectively. The average error rate of the calculated values of the coupled L₂₀(S) calculation model and the measured values in different seasons and weather conditions is below 10%, demonstrating the accuracy and applicability of the realtime calculation method for tunnel access zone luminance in all seasons and weather conditions.
